Description:
The QDE may be configured as a one or two-stage hybrid amplifier. The single stage unit provides 28 dB of gain at the most affordable price. The two-stage QDE offers multiple gains (31, 35 or 38 dB) and exhibits a reduced noise figure with enhanced distortion specifications.
To compensate for the wide range of input and output signal requirements encountered, both variable gain and tilt controls plus plug-in attenuator pads and fixed equalizers have been provided. Test points (-30 dB) are located at the input and output ports to monitor forward and return signal status.
Two way versions of the QDE have options of a passive return path ( -2dB ) or 20 dB gain return amplifier. Plug-in return attenuators and pads are available.
Special 550 MHz QDES models offer a single power-doubledhybrid of 18 or 20 dB gain in both 1-way and 2-way versions. A 5 to 200 MHz, 43 dB gain push-pull model is also available for return path applications. An input pad and equalizer are used to set the signal levels on all QDES amplifiers -- there are no tilt or gain controls. |
